Clipper Windpower PLC, headquartered in Carpenteria, Calif., has announced that the commissioning process is complete for eight of its first full-production 2.5 MW Liberty wind turbines recently installed at the Steel Winds Project near Buffalo, N.Y. The project has been under construction by co-owner/developers UPC Energy and BQ Energy.

In addition, the Liberty turbine will undergo full International Electrotechnical Commission (IEC)-compatible power curve testing later this year at the 100 MW Endeavor wind project site in southwestern Iowa.

According to Clipper, the testing will provide site conditions more conducive to meeting the required, controlled IEC standards, which require an anemometer placement upwind in flat terrain where no site calibration is required. Since current Clipper power curve testing at the Steel Winds site is based on nacelle anemometer calibration, due to the project's close proximity to Lake Erie, an upwind anemometer placement is not feasible.
